Dr. Brian Espey (Trinity College, Dublin, Ireland) has requested photoelectric photometry and bright star CCD photometry of the semiregular variable V2105 Oph beginning immediately. These observations are in support of ultraviolet spectroscopy to be obtained with the Hubble Space Telescope on Wednesday, September 2, 2009. Observations are requested to continue through Sunday, September 6, 2009.

Dr. Brian Espey (Trinity College, Dublin, Ireland) has requested photoelectric photometry and bright star CCD photometry of the semiregular variable NSV 99 (= khi Peg) beginning immediately. These observations are in support of ultraviolet spectroscopy to be obtained with the Hubble Space Telescope in late October and late November 2009. Observations are requested to continue through the end of November 2009.

The stars listed below need additional observations. Please be aware that many of these
stars are difficult to observe, and should be observed only by experienced observers.
Please note that the symbol % after a star name indicates the star has fair to excellent
CCDV or multicolor photometry but still needs visual observations. Because all of the
